We are aware the search results are a little misleading. Here is a little insight into why that is.
A server service updated. As a lot of our code here is custom scripted by myself and some other developers when something updates the configuration can change. The search engine was Sphinx which we started in 2017. As this service needs some extra attention we decided to temporarily enabled the old SQL database search engine which stopped building it's index in 2017. We are working to get Sphinx re-enabled as soon as we can.
